Magento : Region API名称= null

Question

在Magento 1.5中，我调用了region API。它在我的开发环境中工作得很好，并返回以下内容：

[{"region_id":"66","code":"AB","name":"Alberta"},
{"region_id":"67","code":"BC","name":"British Columbia"},
{"region_id":"68","code":"MB","name":"Manitoba"},
{"region_id":"69","code":"NL","name":"Newfoundland and Labrador"},
{"region_id":"70","code":"NB","name":"New Brunswick"},
{"region_id":"71","code":"NS","name":"Nova Scotia"},
{"region_id":"72","code":"NT","name":"Northwest Territories"},
{"region_id":"73","code":"NU","name":"Nunavut"},
{"region_id":"74","code":"ON","name":"Ontario"},
{"region_id":"75","code":"PE","name":"Prince Edward Island"},
{"region_id":"76","code":"QC","name":"Quebec"},
{"region_id":"77","code":"SK","name":"Saskatchewan"},
{"region_id":"78","code":"YT","name":"Yukon Territory"}]

然后，当在我的暂存环境中调用此API时，结果是相同的，只是每个单一名称都是空的，即使id和代码都很好：

[{"region_id":"66","code":"AB","name":null},
{"region_id":"67","code":"BC","name":null},
{"region_id":"68","code":"MB","name":null},
{"region_id":"69","code":"NL","name":null},
{"region_id":"70","code":"NB","name":null},
{"region_id":"71","code":"NS","name":null},
{"region_id":"72","code":"NT","name":null},
{"region_id":"73","code":"NU","name":null},
{"region_id":"74","code":"ON","name":null},
{"region_id":"75","code":"PE","name":null},
{"region_id":"76","code":"QC","name":null},
{"region_id":"77","code":"SK","name":null},
{"region_id":"78","code":"YT","name":null}]

你知道是什么导致了这一切吗？

我不知道，你有没有找到解决方案，但我也有同样的问题。这似乎是magento核心代码中的一个bug (详见region-api)。很明显，这个bug一直存在到3年或更长时间...然而，我找到了解决这个问题的方法：

转到Mage_Directory_Model_Region_Api (在Magento 1.6.2中，此文件位于app/code/core/Mage/Directory/Model/Region/Api.php)中)，并更改以下行：

class Mage_Directory_Model_Region_Api extends Mage_Api_Model_Resource_Abstract
{
    /**
    * Retrieve regions list
    *
    * @param string $country
    * @return array
    */
    public function items($country)
    {
        try {
            $country = Mage::getModel(’directory/country’)->loadByCode($country);
        } catch (Mage_Core_Exception $e) {
            $this->_fault(’country_not_exists’, $e->getMessage());
        }

        if (!$country->getId()) {
            $this->_fault(’country_not_exists’);
        }

        $result = array();
        foreach ($country->getRegions() as $region) {
            $region->setName($region->getName());  // This is the important line to set the name
            $result[] = $region->toArray(array(’region_id’, ‘code’, ‘name’));
        }

        return $result;
    }
}

我建议不要修改核心代码！修复是有效的，但最好是重写文件，或者至少将其复制到本地。

向config.xml添加重写：

<config>
    <modules>
        <Module_Namespace>
            <version>0.1.0</version>
        </Module_Namespace>
    </modules>
    <global>
        <models>
            <directory>
                <rewrite>
                    <region_api>Module_Namespace_Model_Region_Api_Api</region_api>
                </rewrite>
            </directory>
        </models>
    </global>
</config>

将Mage_Directory_Model_Region_Api复制到Module_Namespace_Model_Region_Api_Api并应用第56行中的修复：

class Module_Namespace_Model_Region_Api_Api extends Mage_Api_Model_Resource_Abstract
{
    /**
     * Retrieve regions list
     *
     * @param string $country
     * @return array
     */
    public function items($country)
    {
        try {
            $country = Mage::getModel('directory/country')->loadByCode($country);
        } catch (Mage_Core_Exception $e) {
            $this->_fault('country_not_exists', $e->getMessage());
        }

        if (!$country->getId()) {
            $this->_fault('country_not_exists');
        }

        $result = array();
        foreach ($country->getRegions() as $region) {
            $region->setName($region->getName()); //Fix
            $result[] = $region->toArray(array('region_id', 'code', 'name'));
        }

        return $result;
    }
}
